HUMAN FACTORS ENGINEERING
LESSON 37:
HUMAN FACTORS TEST AND EVALUATION
Well, you've just about made it to the end. You've been introduced to
a myriad of topics on human factors engineering.
You have followed the
bittersweet story of LT Webster and have learned, together with Webster,
what goes into human factors design of equipment. But how do you know if
you've successfully completed your job? Off the top of our heads, we can
give you two possible ways. We could wait until the system is used in the
field. If it works, you are in good shape. A second and more viable means
is through system testing. As you can guess from the title, human factors
testing is the subject of this lesson.
In this lesson you will learn when to conduct testing and the purposes
of HFE testing from a military perspective (AR 70-10) and from the
perspective of professionals in the HFE field (Chapanis and Van Cott).
Next, you will learn about the major types of HFE testing (DT and OT).
Following this somewhat theoretical explanation, you will be provided with
information about various HFE test and evaluation documents.
Before we get into any detail on HFE testing, we want you to take a
moment and gather your thoughts. When do you think it's most important to
conduct a human factors test?
(1) During prototype development. Turn to Page 82.
(2) During the preliminary design process. Turn to Page 76.
(3) When the system is in operation. Turn to Page 96.
From Page 37
(2) You're guessing.
Look at Paragraph 4 in MIL-STD-1472 to get the answer.
